EXERCISING APPARATUS.

Application filed October 1.8.4924. Serial No. 744,489.

To all whom it may concern:

Be it known that I, FREDERICK BAGH, a citizen of the United States ofAmerica, and resident of the city of New York, borough of Manhattan, inthe county of New York and State of New York, have invented a new andImproved Exercising Apparatus, of which the following is a full, clear,and exact description.

This-invention has relation to physical exercising apparatus and hasparticular reference to an improvement in weight pulling machines.

One of the outstanding objects of the present invention is to generallysimplify the construction of apparatus of this type whereby the cost ofmanufacture of the same is reduced to a minimum.

As a further object the invention contemplates in an exercisingapparatus a weight pulling machine, in which the weights are in the formof dumb-bells and are removably associated with the machine whereby thesame may be employed in the capacity of clumbbells. in addition toperforming their function as weights for the pulling machine.

The invention furthermore comprehends a combined weight and dumb-bellwhich is so constructed as to facilitate the application to and removalof the same from the pulling machine. 1 v

l Vith the above recited and other objects in view, the inventionresides in the novel construction set forth in the followingspecification, particularly pointed out in the appended claims andillustrated in the accompanying drawings, it being understood that theright is reserved to embodiments other than those actually illustratedherein, to'the full extent indicated by the general meaning of the termsin which the claims are expressed.

In the drawings Figure 1 is a front view of aweight pulling machineconstructed in accordance with the invention, parts being shown insection to disclose the underlying structure.

Fig. 2 is a vertical sectional view therethrough taken approximately onthe line indicated at 2-2 in Fig. 1.

Fig. 3 is an end view of one of the combined weights and dumb-bells.

Fig. 4 is a horizontal sectional View taken approximately n P1 1 9? india d t 4 4 ill i i 'end of the connecting rod.

Referring to the drawings by characters of reference the weight pullingmachine consists of upper and lower attaching members 10 and 11 whichare of substantially identical construction and each of which isprovided with a pair of alined vertical apertures 12 through which thethreaded opposite ends 13 of a pair of connecting rods 14 extend. A pairof nuts 15 are threadedly engaged with the threaded ends 13 of theconnecting rods for clamping engagement with the upper and lower facesof the attaching members 10 and 11. An elongated sleeve 16 is mounted oneachconnecting rod 14 for vertical sliding movement and each sleeve isprovided at its upper end with a forked bearing element 17 within whichapulley or sheave 18 is mounted. Each connecting rod 14 is provided withan abutment 19 spaced downwardly from the lowermost nut 15 which ispreferably inthe form of a nut threadedover the upper threaded A pulleyor sheave bearing element 20 is swiveled on each connecting rod 14adjacent its upper end by means of vertically spaced apertured cars 21through which the bearing rods 14 extend, said ears being interposedbetween the nuts 19 and 15. An upper sheave or pulley 22 is mounted ineach bearing 20. A yoke 23 is supported from each bearing 20 and thebight portion is apertured toreceive therethrough the knotted terminalof a cable 24 which is then trained around the lower pulley 18 and theupper" pulley 22. The remaining terminal is secured in the eye 25 of thehandles 26 which are provided with the hand grips 27. The sleeves 16 areprovided at their lower'ends with annular enlargements 28 and constitutecarriages for the weights 29. Theweights 29 are of the configuration of.a dumb-bell having the central hand grip portions 30 and knobs 31 atthe opposite ends. The weights are slotted radially inward from one sideas at 32, said slots extending throughout their length and the inner endof said slots being of semi-circular formation as at 33. The slots areof a slightly greater width than the external diameter of the sleeves16. Adjacent the outer ends the dumb-bell knobs are provided withrecesses 34 of greater diameter than the sleeves and of ap roximatelythe same diameteras the en argements 28 at the lower ends 0f thesleeves. Retaining plugs which are axially aper the carriage, theslottedportion is engaged.

The plugs35 are then shifted axially downward into the recesses 254 at the upperends of the dumb-hells to interlock therewith and hold the same inassociated relationwith the carriages.
